My invention relates to a collecting vessel for centrifugals workingunderair-tight conditions, and especiall to the coupling of the pipesfor the materia to be treated with said e collecting vessel. A is Thisnovel collecting vessel is substantially collecting vessel feed anddischarge pipes, lo which are movable axially and at the sametime-subjected to longitudinal pressure, be-

ing coupled to saidpipe bends. l

The advantage of .this novel device lies in the possibilit of cleaninnot only the col- A1&5 lecting vesse, but valso t at feed and dischargepipes, also in the reliable sealing of the pipes with the vessel at thecoupling and connection points, thus securing reliable and simplemanipulation.

The accompanying drawing shows an embodiment of the invention by way ofexample, in Whichq- Fig. l is a cross section and Fig. 2 a plan.

The hinged collecting vessel 2, pivoted at the point 1, is provided withthree collecting chambers 3, 4 and 5 for the discharge and forseparating the materials to be treated, also a feed pipe 7connected-*with the cover` with the collecting chambers', 4 and 5, anda. vertical extension ll ofl the feed pipe 7, are coupled' tocorresponding pipes when the collecting vessel 2 is fixed. Air-tightnessof,

the couplings is secured by the pipes being made movable axially, and bytheir being subjected to pressure through a spring, sealing being thuseffected by them independentlyof one another wlth the possibility ofcompensating for possible faulty workmanf ship and other changes.

'lhe drawing only shows the pipe 12 of the feed pipe 7, said pipe 12being similarly formed as the otherpipes of the discharge bends 8, 9 and10. They are movable axially and ided in the holders 13 which may beattac ed to the casing ofthe centrifugal.

Springs 14 seal the coupling by exerting a` constant upward pressure, ifneed be, by the interposition of a jointing rin The spring, Iiressuremay also be obtarne throughl corcharacterized in that pipe bends arearranged on the one-piece external casing of the hinged 6. Dischargebends 8, 9. and 10, connected respondin ly formed pipe bends and by theyielding o the collecting vessel, also through elastic elements. Theextension 11 of the feed pipe 7 may either be 'rigidly connected withthe pipe 7, or, as shown in the drawing,

it may be a separate piece and likewise arranged to be movable axially,'infwhich case the spring 14 at the same time closes the connectionbetween the extension 1l and the feed pipe 7.

@The pipe couplings of the discharge bends 8, 9 and 10, also the feedpipe l1, are preferably arranged in proximity to the pivoting point 1,thus enabling the collecting chambers to be drained when tilting thecollecting e5 vessel 2. In the open position the remaining Vcontents arereturned to the respective pipes through drip troughs 15 disposed on topof the pipes. The drip troughs may be omitted in certain positions. InFig. l the dripping 7o position is shown by chain-dotted lines. If

, the couplings are in alignment, or in a similar position relative toone another in proximity to the pivoting axis, the application of thepressure for tightening the Joint is fa- I cilitated by reason ofthegreater leverage so that in most cases the deadweight ofthel collectingvessel suffices to produce the tightening pressure. Moreover, adjustmentis hereby inore easily effected in case the spring 8g pressure isobtained by the bendsor other auxiliary means with limited spring-pressure. The pivot l is preferably openat the back to permit the wholecollecting vessel 2 being lifted off while in the raised positionwithoutoslackening the bolt. Ifthe deyice is to be cleaned, the cover-6,which -is secured by screw clamps, is vtaken ofi', 'and the collectingbottoms, which are loosely fitted, re-

moved separately. lThe outside edges of the v ment,-the possibility isgiven of extending the outer casin of the collecting vessel over allcollecting c ambers without any1 interruption, and thus locating thedischarge bends in an unchaneable, secure position 5 relative to oneanot er without imyairin the cleaning of the dischar e bends. peciajointings between the col ecting chambers may be dis ensed with, and thecollecting vessel may e made of great strength, a fam vorable point ofthe invention. The invention is also applicable without the hin e 1, inwhich case the collecting vessel 2is li ed off vertically in the knownmanner.

In all cases the ossibility7 is given of thoroughl)T cleanin t ecollecting vessel and the ipes, combine with easy and safe manipuation.

What I claim is 1. A feed and collecting vessel for centrifugalapparatus, comprising an integral outer casing having a plurality oftroughs one over the other and decreasing in size .from the bottom tothe to a collecting chamber lid for each troug a pipe connected to eachtrough decreasing in size from the top to the bottom; a cover` for thecasing; and a pi e secured to the center of the cover.

2. A eed and collecting vessel for centrifugal apparatus, comprising anintegral outer casing having'a plurality of troughs one over the otherand decreasing in size from the bottom to the top; a collecting chamberlid for each trough; a pipe connected to each trough; a cover for thecasing; and a pipe secured to the center of the cover, each pipe havinga drip, trough to permit axial movement of the pipes. I
